Presentation API Proposal

[Kully]

Presentation API Proposal - a wrapper that is built similarly to the Dashboard one.
-add a presentations.py file in plotly/api/v2/ for requests (https://api.plot.ly/v2/spectacle-presentations)
-make a presentations_objs file or something with a similar title
-add py.presentations_ops class to py

For visual feedback, Jack suggested something that looks like this: http://rmarkdown.rstudio.com/ioslides_presentation_format.html
and only supporting a few layouts for a first pass.

For tests, as with Dashboards, letting the backend yell at me if the JSON of the presentation is bad seems good enough for the first pass.

Any other suggestions? 😄

Sounds good to me. FWIW, I'm not sure if the backend has validation for presentations in yet.

Okay, so I may have to add proper tests

It might make sense to use this markdown format since it already has a precedent in technical computing:

In Jupyter, users could write their presentation in markdown, copy that markdown to a string, then pass the string to a class that converts the markdown to Spectacle JSON and POSTs it to Plotly.

@cpsievert - you've used this ioslides module from RStudio, right? Anything you wish it had?

[cpsievert]

Yep, but I'm actually thinking of moving away from ioslides towards this remark-js based rmarkdown presentation template -- https://github.com/yihui/xaringan

I mainly want to switch because the default styling looks way better, and I'm no CSS wizard.

[jackparmer]

Maybe we should use this markdown format instead then: https://github.com/gnab/remark Looks ~95% the same as ioslides anyway.

Love this idea. Simple for users to use.

@cpsievert This seems to be the case for a lot of folks. We should ship this with a few default themes available, maybe based in these ones? Any others?

@Kully so maybe the workflow is something like this?

import plotly.presentation_objs as prez
import plotly.plotly as py

markdown_string = '''
# Title

---

# Agenda

1. Introduction
2. Deep-dive
3. ...

---

# Introduction
'''

my_presentation = prez.Presentation( markdown_string, theme='moods' )

url = py.presentation_ops.upload(my_presentation, 'My First Presentation with Python')

I like all of these Jack. We could even allow for custom templates that get generated when you give a list of 3 or 4 colors to create the theme, eg. [#fafafa, #04aaaa, #0000ff]. ColorHunt has a lot of good schemes.
